In 5G/6G wireless networks, user devices and base stations may adjust their transmission power according to the distance to the recipient, and thereby provide sufficient reception without wasting energy or generating interference. User devices can determine their own location by GPS, for example, and transmit that data to the base station so that the base station can adjust its downlink power accordingly. Likewise. base stations can transmit their location coordinates to user devices in, for example, a system information message. Sidelink, or V2V and V2X, messages can likewise be power-adjusted after user devices exchange their location coordinates. Mobile user devices can also indicate their speed and direction of travel, so that the base station or other user devices can calculate the changing distance and compensate power accordingly. The method may enhance reliability by providing that messages arrive at the recipient with sufficient amplitude for reception, and may provide low latency by avoiding the time-consuming power scan, while avoiding delays for retransmissions and the like.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the message is transmitted according to 5G or 6G technology.
3. The method of claim 1, wherein the message indicates the location of the mobile user device.
5. The method of claim 1, further comprising specifying, in the message, an identification code of the mobile user device.
8. The method of claim 6, wherein the determining an enhanced power level comprises reading, from a non-transitory computer-readable memory, a previously determined attenuation level or a previously determined transmission power level.
9. The method of claim 6, wherein the determining an enhanced power level comprises determining, from a map, a previously determined attenuation level or a previously determined transmission power level.
16. The first mobile user device of claim 14, wherein the first message includes a period of unmodulated carrier signal.
